ANIMAL-RELEASING DEVICE.

SPECIFICATION forming part of LettersPatent No. 373,434, dated November 22, 1887.

Application filed September :2, 1887.

To all whom, it may concern:

Be it known that we, Luwrs BRAHAM, a subject ofthe Queen of Great Britain, now residing at Titusville, in the county of Crawford and State of Pennsylvania, and HENRY L. K. JACKSON, a citizen of the United States, residing at said Titusville, have invented a new and useful Improvement in Animal-Releasing Devices for Horse-Stalls, of which the following is a specification.

Our invention relates more particularly to stalls where each one is one ot a series, as in stables where large numbers of horses are kept, but is applicable to smaller stables or where only one horse is kept, our object being to provide an easy and quick device by which each separate horse can be led from the stable and released in time of danger, as fire, &c. Ve accomplish this by making in the side wall ofthe building and in front of the stall a door large enough every way to allow the passage of the horse, the doors being adjacent to each other,

and each is so constructed and arranged that by asimple withdrawal of a bolt the door opens outward,leading the horse to the open air,and then releasing it. Ve also provide for the simultaneous withdrawing of the bolts to all the doors.

Our invention is illustrated in the accompanying drawings, in which- Figure l shows the outside or front of the stable, having four adjacent stalls, with the doors all closed, also showing the device for opening the doors simultaneously; Fig. 2, the same view with the doors open and the horses coming out; Fig. 3, a sectional plan view ofthe front of one stall with the door closed and fastened,showing the device for hitching the horse; and Fig. 4, the same with the door open and the halter automatically released.

The same or similar parts are indicated in the several views by the same letter.

A is the outer wall ofthe stable; B, the doors, one in front of each stall, each opening outward. Each door is now shown as held shut, Fig. 1, by a bolt, C, passing through the two staples D D, the bolt passing over the hasp E, which is firmly secured to the door B. On the hingepost of the door is attached the spring F, one arm of which extends partly across the door and under the elongated staple G. The spring Serial No. 249,617. (No model.)

is set so that when the door is released by withdrawing the bolt C the spring opens the door.

At one corner of the building is attached the lever H, pivoted near the ground,and attached to this lever is the cord I, running along the side of the building under the doors. At each door-post it is attached to one arm ofthe bellcrank K, each crank having a wire from its other arm connecting with the lower end of the bolt C. By the movements ofthe leverH pulling the cord I and communicating through the bell-cranks K, the bolts C are simultaneously withdrawn, and the doors, all being released, are opened by the springs F and take the position shown in Fig. 2. On the inside the door B forms the head of the stall. At a convenient height are placed the studs L L' L,(shown in Figs. 3 and 4,) perforated to admit the sliding bolt M. To the rear end of this bolt is attached the cord N,which in turn is secured to a staple, O, in the door-post. The length of this cord N is so adjusted that when the door is closed the bolt M is allowed to pass through the eX- terior stud, L; but when the door swings open the foreshortening of the cord N withdraws the bolt, and when the door is wide open the end of the bolt is withdrawn till it is flush with the face of the stud L. The ring I?, to which the halter is attached, is placed around the bolt M, between the studs L and L. This holds the halter securely when the door is closed; but as the door swings open, the bolt M being withdrawn, the ring P is released and the horse is free; but, as the bolt M is not entirely withdrawn, so as to release the ring l?,till the door` is nearly wide open,the horse, by the opening of the door, is led forward toward the open air before being released.

We have here shown and described one device for communicating the movement of the lever H to the withdrawal oi' the bolts O. Other similar well-known devices may be used, andthe connecting-rod may be carried over the tops ot' the doors and the bolts drawn up instead of down, none of these slight changes materially changing our device; also, other devices for opening the doors other than spring, as cord and pulley and weight.

Ve claim as our invention- 1. The combination of the pivoted lever H, the connecting-rod I, the bell-cranks K, the

IOO

upright rods or cords connectingthe cranks K to the bolts G, and the bolts C, all operating together as a device for simultaneously releasing the fastenings of the doorsv ina series of stalls, substantially as shown and described.

2. The combination of thepivoted lever H, the connecting-rod I, the bell-cranks K, the upright rods or cords connecting the cranksK to the bolts C, the bolts C, and the springs F, all operating together as a device for simultaneously opening the doors in a series of stalls, substantially as shown, and for the purposes herein set forth.

3. The combination of the studs L, L', and L, the sliding bolt M, the cord N, connecting the bolt M to the door-casing, and the halterring P, as a device for releasing the horse when the door is swung open, substantially as shown and described.

Ythe purposes herein set forth.
